[56.01] Depolarization Analysis of 13 FR II Radio Galaxies and 13 QSRs

I. Fernini (United Arab Emirates University)

Two statistically complete sample of 13 FR II RGs and 13 QSRs are compared in terms of their polarization properties. Previous papers [Fernini et al. (1993), AJ, 105, 1690; Fernini et al. (1997), AJ, 114, 2292; and Bridle et al. (1994), AJ, 108, 766] have found that the jet detection rate in the 13 RGs stands at only two with no counterjets, whereas the jet and counterjet detection stand at 100% and 50%, respectively, for the 13 QSRs. Moderate depolarizations asymmetries between 6 and 20 cm are found between the lobes of the RGs compared to the strong asymmetries in the QSR sample. These results are then used to test the RG/QSR unification scheme of Barthel [ApJ (1989), 336, 606].
